Tone() working once

[claudejaspart]

Hello,
I have a program that should make a beep whenever it receives a particular NEC code. It only works once, then the program fails and does nothing.
Here's the code :

#include <irmpSelectMain15Protocols.h> 
#include <irmp.hpp>
#define IRMP_SUPPORT_NEC_PROTOCOL        1 

int buzz = 11;
IRMP_DATA irmp_data;

void setup() 
{
    irmp_init();
}

void loop() 
{
    if (irmp_get_data(&irmp_data)) 
    { 
        if (irmp_data.command == 247)
        {
            tone(buzz, 1760, 200);
            delay(1000);
        }
    }
}

Thanks for the help

Ok i found that I need to use irmp_init(); right after using the tone() function.
It works.
